But the very fact that you are still speaking to him must be reassuring to him that you are not one of these shallow people who only go after good looks, so keep going - you never know, it could work out well for you both.
As for photos - people often don't really look much like their photos anyway. I blinkin well hope that I don't because I am the most unphotogenic person in the world.................or maybe I really do look like that.........which is very depressing
I definitely say meet him. You'll always regret it if you don't.
